AXLE-ADJUSTING DEVICE.

Application led March 24, 1923.

To all 207mm it may concern:

Be it known that I, W'ALTER R. STRUNK, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Axle-Adjusting Devices, of which the following` is a specitication.

This invention relates to improvements in axle adjustment and it pertains more particularly' to a means for pitching or setting the front axle of a vehicle at the desired angle for easy or non-quivering driving.

The invention is intended more partienlarly for use on Ford or like cars, in which it is necessary to pitch the front axle sli `ejhtly forward at the upper side. when the most satisfactory steering is to be secured.

Ordinarily, the radius rod is bent, to secure the desired pitch iu the axle, but this is unsatisfactory in many ways, aud to overcome this, I have devised a simple invention in the form of a pair of like washers or dises. slightly tapered, and each provided with a lip projecting from the periphery, so that` when the pair of discs is placed beneath the axle, between it and the end of the radius rod, the proper pitch or adjustment of the axle may easily be secured by simply turning the discs.

The invention is more fully described in the following specification and cleat 'y illustrated in the accompanying drawing', in which:

Figure 1 is a sectional view through au axle and the forward end of the radius rofl, with my invention applied thereto.

Figure 2 is a sectional view through --2 of Figure 1.

The numeral l designates a vehicle axle ot' simple form, and the spring,T perch, whose bolt or stem passes downwardly through the axle and is provided with a suitable uur t5.

This nut usually secures the forward end 4 of the radius rod 5 to the under side of the axle, but in my present ease I interpose between the end of the radins rod and the under side of the axle, a. pair of like dises or washers, surrounding the bolt.

These dises G are each formed with a thumb engaging lip T at one point on its periphery, and the Hat surfaces of the discs are tapered with relation to each other7 so that, when the discs are in position, and it is desired Serial No. 627.386,

to throw the upper side of the axle forward, the discs are turned by pressing the lips either toward or away from each other, and this movement 'will raise or lower the inner lower edge of the axle with relation to the fiat upper surface of the inner end of the radius rod, and thus give the axle the desired pitch necessary for easy steering'.

It is evident that in some cases, a single disc may be used with fairly good results, or that one fiat and one tapered disc may be used, but. in any case, the object is to increase the distance between the inner lower edge of the axle and the upper edge of the radius rod, when it is desired to throw the upper end of the axle forward.

The device is easily applied. costs very little, to manufacture, and accomplishes a very desirable object inasmuch as one of the very disagreeable features of steeringr the light ears is due to the so-called shinnnying or unsteady action of the front axle, due to bent radius rods or other causes.

Writh my improved device, any such irregularity may be easily overcome and the attempt to iestore the parts to normal position by bending the radius rod is no longer necessary, as the discs will take up the irregularity whether it. is slight or deeided.

The discs may be made of any suitable material.

Having thuse fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a device for adjusting vehicle axles, the combination of an axle, a radius rod, a bolt passing;` through the axle and the end of the radius rod, a nut adapted to draw the axle and the radius rod together. and a tapered. rotatable member interposed hetween the axle and the radius rod` whereby the angle of the axle with relation lo the' radius rod may be changed.

2. In a device ot' the character described, an axle, a radius rod, a bolt and nut for securing the radius rod to the axle, and a pair of tapered dises interposed between the axle and the end of the radius rod, and surrounding the bolt, whereby the turnintr of the discs will change the angle of the axle with relation to the radius rod.

In testimony whereof I affix my signature.

WALTER R. STRUNK.
